Question

Name two commonly used devices which use polarize light?

Answer 1

The first of the two categories into which polarizaton devices are divided includes simple devices for the production and conversion of polarized light—for example, linear and circular polarizers, phase plates, optical compensators, and depolarizers. The second category of polarization devices comprises more complex structures and equipment for quantitative optical polarization investigations. The components of such devices include polarization devices of the first category, light detectors, monochromators, and auxiliary electronic devices.

Answer 2

Analyser and polariser are the substances which are used to polarise the light
